hi all, wife and I had contemplated for some time switching from our woodstove to a pelletstove so when this stove came along at a local thrift store at a great price I bit the bullet to make the move. Their comment was the donor had said it was working when removed. It does seem to be in great shape but when I plug it in the small display screen simply keeps changing thru various numbers and letters and the off/on button seems to have no effect. Is there a trick to reset the control or am I out of luck ? The replacement boards for these things are scary expensive ! Can they be repaired ? I "might" be able to take the stove back but I'd prefer to get it going and stay the course. Thanks for any help you can offer. We're located in northern VT.
